The answer is x³ - 9x² + 23x - 12
Let's use distributive property method:
(x - 4)(x² - 5x + 3) = x * x² + x * (-5x) + x * 3 - 4 * x² - 4 * (-5x) - 4 * 3 =
= x³ - 5x² + 3x - 4x² + 20x - 12 =
= x³ - 9x² + 23x - 12
Answer:
x = -7 and x = 4.
Step-by-step explanation:
f(x) = x^2 + 3x - 28
= (x + 7)(x - 4).
The reciprocal of f(x) can be written as
1 / (x + 7)(x - 4).
When the denominator is zero we have vertical asymptotes
so they are x = -7 and x = 4.
Answer: c > -25
From the question you can get the equation:
5 - 3c > 80; subtract 5 from both side
-3c > 75; divide -3 from both side
c > -25
So numbers including: -24, -23, -22, -21…
are all numbers that could work
123 bracelets ...
fixed costs $825 and each bracelets costs $1.25. she only makes back $6.75 each bracelet. In order to make a profit she has to earn back the $825. 825/6.75 = 122. she needs to make 122 bracelets to break even but it will take 123 bracelets to make a profit
